Research on the Effectiveness of Lidar Survey for Large Mapping

Abstract. The analysis of the time spent on the processes and the complex of works on topographic mapping in accordance with production projects is given. The projects were carried out according to traditional technological schemes of work and technological schemes using airborne laser scanning materials to generate digital topographic plans at scale the 1:2000 based on the use of unmanned aircraft. The comparative performance of the technologies was determined based on taking into account the time spent for field and in-house work. When using air laser scanning data in addition to air photography, there is an increase in work productivity.
